Almina Carnarvon acted as Matron at two war time hospitals between 1914 and 1919.

She created Highclere Military Hospital which opened up in 1914 soon after there were any wounded to treat. Later, she moved her activities to London to 48, Bryanston Square, which operated until after the Grear War ended.

In 1927, in part to aim to retore her damaged reputation, after the mud-racking sex scandal revealed in the hard fought legal case of Dennistoun v Dennistoun, in 1925, Almina opened Alfred House, a nursing home based at 7-9 Portland Place, London, which ran until the start of the Second World War.

Almina had two further homes after this, based at Hove and Barnet, finally ceasing as a hospital proprietor in 1943.
